334

337     });
338 });
339 </script>
340 </body>
341 </html>

看331行，点击提交时，用&nbsp;

$('#defaultForm').bootstrapValidator('validate');

触发表单验证
&nbsp;
下面是碰到的一个坑：
bootstrapValidator默认逻辑是当表单验证失败时，把按钮给变灰色。但是项目中，button并不在form内部，是通过事件绑定来ajax提交的。那么问题来了：
项目需要当form验证失败时，不执行所绑定的后续事件。百度半天找不到相关资料，最后还是要靠google：

$("#yourform").submit(function(ev){ev.preventDefault();});
$("#submit").on("click", function(){

   var bootstrapValidator = $("#yourform").data('bootstrapValidator');
   bootstrapValidator.validate();
   if(bootstrapValidator.isValid())
     $("#yourform").submit();
   else return;

});

酱紫就可以判断表单验证是否通过了。
